EPENTEDON new genus. 
Female: — Head a little wider than long, the antennee inserted below the middle, 10- 
jointed, three ring and funicle joints, the distal joint of club terminating in the usual distinct 
spine. Mandibles bidentate. Prox)odeum distinctly tricarinate, the median carina bounded on 
each side by a sulcus whose lateral margin is earinated, forming three converging carinse on 
the j)ropodeum; lateral carina) ju'csent. Sontellum simple. Second segment of abdomen occupy- 
ing a third of the surface, the others much shorter. Parapsidal furrows comx)Iete, deep and 
distinct, narrowing cephalad. Pronotum transverse. Petiole of abdomen somewhat longer than 
wide. Marginal vein nearly twice the length of the submarginal, the jmstmarginal vein 
elongate, over twice the length of the sessile but long-elliptical stigmal, about a third the length 
of the long marginal. Jlind tibial spur normal. Like FelorofelopscUa Girault but the post- 
marginal vein elongate, three ring-joints, lateral carina3 i>resent. Like Pleurotroppopsis but the 
median carina of ijropodeum is Ijoundod by sulci. 
Male: — Not known. 
1. EPENTEDON UNNOTIPENNIS new species. Genotype. 
Female: — Length, 1.70 mm. 
Metallic blue-green, rather dark, the wings hyaline but with a rather large, ovate smoky 
brown sjjot ajjpended from the knob of the siigmal vein and extending across the wing nearly 
to caudal margin but most distinct as a round sjiot under the stigma. Legs yellowish brown, 
the coxa) coucolorous, the antenna) wholly concolorous; second ring-joint very short, the others 
large; funicle 1 longest, 3 a little larger than the x^edicel, oval, shorter than L Second tooth 
of mandible truncate mesad. 
Prom one female reared from deshy galls on gum, March 20, 1911 (P. P, Siwy). 
Habitat : Melbourne, Victoria. 
Type: — In the National Museum, Melbourne, the above specimen on a tag, the head on 
a slide. 
LEROSTENOILES new genus. 
Female: — Like Neodcrostenus Girault but the proj^odeum with a curved lateral carina 
whose mesal side is deeply snlcated. Mandibles strongly bidentate, the inner edge of the inner 
(mesal) tooth with five or six fine teeth like the inner tooth in the mandibles of many Elachertini. 
Meson of j)ro|iodeum polished, convexed. Antenna) with two ring-joints, the club 2'jointed, the 
anteniuD 9-jointed, inserted somewhat below the middle of the face. Segment 2 of abdomen 
occujiyiug about a fourth of the surface, longest, the petiole short. Postmarginal and stigmal 
v’eins short, subequal. Parapsidal furrows eomx)loto, extraordinarily thin, the scAitura eejihalad 
declivous, the pronotum ahftcnt (not visible from above but the suture between the pro- and 
mesothorax is on the neck). Hind tibial sx>ur normal. Axilla) advanced barely at all. 
Male: — ^Not known. 
1. DEROSTENOIDES NEGLECTUS new species. Genotype. 
Female: — Length, O.SO mm. 
Dark metiillic green, the wings stained rather deeply, the legs, scape and pedicel reddish 
brown (coxso metallic), the pedicel suffused with dusky. Thorax nearly black, with polygonal 
reticulation, the lines not raised, somewhat coarser on the scutellum which has a smooth spot 
centrally at base. Punicle joints more or less globular and subequal, the second a little the 
largest. Inner margin of first tooth of mandible minutely, slightly serrate. Pedicel longer 
than funicle L 
Described from one female collected by !Mr. A. M. Lea. 
Habitat: Cairns District, Queensland. 
Type: No. Hy^485, Queensland* Museum, Brisbane, the above specimen on a tag, the
